Solving for variable 'm'.

Begin completing the square.

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + -11m + -1 + m2 = 0 + -1

Reorder the terms:
1 + -1 + -11m + m2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -11m + m2 = 0 + -1
-11m + m2 = 0 + -1

Combine like terms: 0 + -1 = -1
-11m + m2 = -1

The m term is -11m.  Take half its coefficient (-5.5).
Square it (30.25) and add it to both sides.

Add '30.25' to each side of the equation.
-11m + 30.25 + m2 = -1 + 30.25
